Intel to ship 1.8GHz Centrino as Pentium M 545

A feast of model numbers

Intel hasn't been backward in coming forward about its upcoming 32-bit microprocessor naming scheme, but it's kept mum about the finer details. Yes, desktop Pentium 4s will ship as 500-series chips, but how will a specific chip - the 3.2GHz model, say - be labelled?

According to DigiTimes, that chip will be the P4 530, citing Taiwanese mobo maker sources.

The 2.8GHz model will be the 520 and so on up the list in intervals of ten to the as yet unannounced 4GHz P4, or the 580 as we should call it. And here are the rest:

Mobile Celerons and Mobile Pentium 4s will also ship as 300- and 500-series parts, though Intel stresses the mobile and desktop numbers will not be directly comparable. A case in point: the Pentium 4 Extreme Edition will, like the Pentium M, be branded as the 700-series, but there's clearly a very big architectural and performance difference between the desktop and mobile lines. ®
